If i feed my cats homemade food will they not eat their store bought cat food?

3 of my cats will eat wet food, my other female only eats dry. I heard its good to at least give them a little wet. I have some receipes that include chicken, carrots, etc. I just dont want my little ones to get spoiled. Maybe for a special dinner once in awhile. Thanks fellow cat-lovers. Oh, ive tryed so many wet store brand foods to the most expensive Roxy will not eat it.
